As an anthology series, Into the Dark doesn't have a set plot. Instead, it's closer to a huge collection of separate horror movies, each inspired by a holiday. Fortunately, that gives us some insight into the potential structure of season 3. 

The first two seasons opened with a Halloween-themed episode on September, followed by a Thanksgiving one in October, then Christmas and New Year's Eve ones in December. Other episodes follow this theme, though the holiday they pick can vary. Apart from borderline unavoidable holidays, like Valentine's day, Mother's day and Independence Day, the show has been known to avoid predictability by often dipping into lesser-known themes like Pet Appreciation Week, and Father-Daughter day. 

Still, if you had to make a guess about a specific storyline, it would probably be worth betting on the return of Pooka, the creepy children's toy that has become a series mascot of sorts. The first season's Christmas episode, the aptly-named "Pooka!," introduced us to the maliciously malfunctioning Pooka toys, as well as Wilson (Nyasha Hatendi), an unemployed actor who becomes inseparable with his life-sized Pooka mascot suit. The following season's "Pooka Lives!" turned Easter into a fictional "Pooka Day," where a group of friends create a Pooka-themed holiday and a viral challenge, which unfortunately causes murderous, increasingly strange Pookas to come to life. Episodic and unrepetitive as Into the Dark is, a third, hopefully even freakier visit to the Pooka well would be most welcome.
